We're pretty sure if you took a tour of the thousands of AT&T stores across the country, you will find tons of sloppy displays, errors, etc. Anyone who has ever managed retail knows the difficulty in trying to control appearance, which is why chains employ internal checks, secret-shoppers, etc.
In that case, perhaps this AT&T store in Florida is not that different and we're just picking on a single case. But using the original Samsung Focus as the display phone for the brand new, much praised Focus S is a bit much (we're forgetting for a second the lack of display card too). And while mistakes and sloppiness like this are sure to happen on occasion, Windows Phone simply cannot afford to have instances like this occurring.
Update: Reader Justin A. sent us this photo from another AT&T store. Here they are mixing up the Focus S for the Flash. Sigh.
Big thanks to Jack F. for the photo!
